To all whom z't may concern: Be it known vthat l, GERMAINE Mona Loose, a citizen of' Belgium, and a residentot the city of New York, borough of Manhattan, in the county and ltritate of New York, have invented a new and Improved l/Vater Heater, of which the following is a lfull, clear, and exact description. c

This invention relates to a water heater, and has for an object the provision of an automatic water heater which is extremely simple in its operation and construction whereby the cost ofV manufacture and repair is reduced to a minimum.

Another object resides in the provision of means whereby the heating fluid` is cut oil automatically whenever the flame, especially the pilot llame, goes out. Y

A further object resides in the provision 2o of thermostatic means responsive to changes in temperature to actuate magnetic means to close the gas valve under predetermined conditions.

A still further object resides in the particular construction and arrangement of parts' which are hereinafter described and claimed and shown in the `accompanying drawin The invention is illustrated in the drawin?, in which-.-

igure 1 is a vertical section through the heater.

Fig. 2 is a vertical section through the cas in containing the water and. fuel valve, ta en on the line 2-2 of Fig. 1.

3 is a horizontal section taken on the line 3-3 of F ig. 2.

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction 'and arrangement of the parts and inthe character of the materials used may be' adopted without departing from the spirit of the invention.

' rlhe apparatus comprises a casing 1 of any suitable material within which is disposed a series of coils or pipes 2, preferably copper pipe, and preferably disposed on the form of a hollow tapered Icone. These coils 5o or pipes have connected thereto an outlet pipe 3 and an inlet pipe 4. This s iral tapered coil of piping is surrounded y a conical tapered sheath of any suitable metal 5 and also has a plurality of beveled plates 'at euch as 6 and 7 supported horizontally with a suitable circuit.

throughout its height within the coil I to spread the heat toward the pipes and away from the center of the coil. The casing 1 has an outlet draft pipe 8, and the water coils 2 are supported on suitable brackets 9 attached to the inner face'of the casing 1. Supported beneath the coils vonsuitable brackets 10 is a heater pipe 11, which is preferably supplied with'- gaseous fuel and automatically lighted by a pilot burner 12 of any suitable construction. rlhe heater pipe 11 is connected 'by a pipe -13 with a cylindrical casing 1t. A pilot burner 12 is connected bya pi e l'with an elbow 16 leading to a gas cham er supplied with, preferably, gaseous fuel through a gas pipe 17. To the pipefl adjacent' thepilot burner`12 is disposed a thermostatic device 18 whichy is preferably in the form, of a bimetallic strip.

rl`his device, when it has become deflected,V

moves downwardly'to engagewith an adjustable contact 20 on a bracket 19 insulatingly supported from any suitable point. A lever arm 21 pivoted at 22 can be operated by a handle 23Y disposed outside the casing 1 to lift the thermostatic arm 18 oil1 the contact 20 and direct the circuit when desired and for the purpose hereinafter Set forth. rlhe bracket 19 is connected by a wire 24 rlhe thermostatic element 18 is connected by a wire 25 to the saine circuit in the 'manner hereinafter set forth. When the arm 21 is moved by the handle 23 to lift the thermostat arm 18, the frictional engagement between the two with the arm 21 in a vertical position will hold the arm 21 in this position. As long, therefore, as the thermostatic armis cold, which occurs when' the pilot light is out, the arm 18 will be held upward. Whenever .the pilot light, however, is lit, the thermostatic arm will be ai'ected so that it will automatically move upward. By moving upward it will become disengaged from the lever 21, whereupon the weight of the -handle 23 will cause the lever 21 to drop, thus moving out of the path of the thennostatic arm 18 when this arm again becomes cold. .By reason of this operation it will be Seen that when the handle 23 has once been operated and the -valve 38 lifted oli its seat by means of the ring 46, as hereinafter described, the valve will be held upward.

rlhe cylindrical casing 14, which is in reality a valve casing, contains a water-oplll@ eratedl valve normally disposed on a seat 27 andy provided with astern'28. y A water inlet pipe 29 leads to a chamber beneath the 'valve seat 27. The stem 28 extends through av packing vgland into an o en chamber within the valve casing 1d and is provided with a spring 31 disposedv between the packing gland and a collar 32 iixed on the stern28. This spring tends to hold the valve 26 normallv on its scat 2. rlhe valve 26 .is preterably made ot' brass and the seat 27 is also made out brass, so that no packing between the valve and its seat is required.-

A. partition 33 dis osed across thelower portion of the cylindrical casing lll separates theintermediate chamber from a lower gas chamber. 'The stern 28 extends through a packing gland 34 into this gas chamber and has on its lower end a valve 35 adapted normally to be seated on a seat 36 @Whenthe valve 25 is disposed on its seat. The gas chamber beneath the partition 33 is supplied with gas through the pipe 17. This pipe `l1'? leads to an elbow to which is connected a Vgassupply pipe 39. Within this elbow is disposed a seat 37. :tor a, valve 38 which, when it is disposed on the lseat cuts oli the supply of gas to the apparatus. This valve has a stem i0 extending upwardly' through a packing gland 41 into a chamber d2 formed in the casing'. `This stern l0 vhas attached thereto a collar i3 between which and the upper end ot'a cover plate 50 a. spring lll extends to normally force the valvel 38 down on its seat. The upper end of the stem l0 is provided with a head 45, preferably formed in the shape of .a truncated cone with the theoretical apex pointing downward. This head is also-supplied witha finger ring 46 'and is normally disposedbetween two spring plates 47 and 48 connected at one end to a box 49. This box 49 is supported from the cover plate 50 which extends over the top of the casing d2 and contains a magnet 51. Thisjmagnet is adapted to actuate a latch lever 52 containing a latching Engeri 53 to be disposed iinderneath the lower edge of .the head d5.'

The lever 52 is ivoted at 5d and is held normally outward by reason of the spring 55 connected 'to its lower end. rlhe battery the wire 25. 'lhe wire 25 is connected to 55' 56 is in 'series with the magnet 51, with the bracket 19, the thermostatic element 18 and the plate 48, and this-plate is normally in 4cir-inrit with the plate 47 through the head 45, the plate 47 being connected 'to the other side of the magnet 51 by a wire 57.

From a consideration of lig. 3, which represents this circuit, it will be seen that insane? down on its seat.4 `When the valve 38 is thus disposed on its seat the gas is shut od. This action of the valve takes place Whenfever the thermostat-ic element contacts with the adjustable screw 20 on the bracket 19. This contact is made Whenever the heat of the. pilot burner drops below a certain value, especially when the pilot burner goes out. ln this way an absolutely accurate means is provided which will cause the gas to be shut oil as `soon asthepilot burner goes out, and thus the danger, of gas escaping without being burned is positively void.

The apparatus, itwill be seen, is simple in its construction and operation and cons'equentlyrequires .very little attention, needs yvery little repairing, and could be economically manufactured. The construction of the water coils is suchthat heat is mostellcientlydisposed along the coils coming intimately into contact therewith. The gas is turned on automatically as soon as the water commences to flow but is very quickly shut oil the instant the water ceases to How, so that no more than the necessary amount of water is heated at any one time.

uWhatv l claim is:

1. A watertheater which comprises a pilot light, a thermostatic element associated therewith. and movable in accordance with the variations in the condition of the pilot light,
